Frequently Asked Questions

Why did my Husqvarna Automower show Error 27?
Error 27 appears after a factory reset has been completed, either intentionally through the menu system or automatically due to a software issue. It's simply confirming that all settings have been restored to defaults.
Will I lose my boundary wire settings with Error 27?
No, the physical boundary wire installation remains unchanged. Error 27 only resets software settings like schedules, cutting height, and PIN codes. The mower will still recognize your yard's boundaries.

Error 27 typically only appears after intentional factory resets or software updates. Avoid unnecessary factory resets and keep your mower's firmware updated through the Husqvarna Connect app to prevent software glitches.
Can I restore my old settings after Error 27?
Unfortunately, you cannot restore previous settings after a factory reset. You'll need to manually reconfigure all preferences including schedules, cutting height, PIN, and app connections.
Is Error 27 dangerous for my Husqvarna mower?
No, Error 27 is not dangerous and doesn't indicate any mechanical problems. It's simply an informational message letting you know that settings have been reset and need to be reconfigured.
